Place the most important words at the beginning

A whopping 50% of emails are now read on mobile phones, said Dmitri Leonov, a VP at email management service SaneBox.

Since you don't know how much of the subject line hiring managers would be able to see from their smartphones, it's important to put the most important information at the beginning of the subject line. Otherwise, compelling details could get cut off.

Include the position and your name

For a standard job application, Augustine said the most important information to include in the email subject line is the job title and your name, as well as the job's ID if it has one.

Anything less will require the hiring manager to spend time opening the email and trying to decode it.

Example: Data Scientist, No. 123456 — John Smith Application

List your designations to show that you're qualified

The subject line should be a place to distinguish yourself and immediately catch a recruiter's eye.

Augustine said to include any acronyms you have that are pertinent to the job. For example, you might add MBA, CPA, or Ph.D. after your name, depending on its relevancy to the position.

Example: Marketing Director — John Smith, MBA

If someone referred you, be sure to use their name

If you've been referred by a mutual acquaintance, do not save that for the body of the email, said Augustine. Put it in the subject line to grab the hiring manager's attention right away.

Moreover, she suggests beginning the subject line with the person's full name.

Example: Referred by Jane Brown for Technical Writer position

Don't use ALL CAPS

Using all caps may get someone's attention, but in the wrong way. It's the digital equivalent of yelling, and your job is to make the email as easy as possible for a recruiter to read rather than giving them anxiety, said Leonov.

Instead, use dashes or colons to separate thoughts, and avoid caps and special characters like exclamation points.
